CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 319,389, dated June 2 1885.

Application filed April 22, 1885. (N model.)

To all whom it may concern.-

Be it known that I, J osEPH BUTTON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Car- Couplings, of which the following is a specification.

My invention relates to improvements in car-couplings, and will first be described and then claimed.

The accompanying drawings illustrate the invention, Figure 1 being a view of a car to which the improved coupler is applied. Fig. 2 is a longitudinal section of the draw-head, showing the link coupled to the pin. Fig. 3 is a similar view showing the position of the pin and other parts when the link is about to be coupled. Fig. 4 is a top view of the drawhead and coupler. Fig. 5 is a front view of the draw-head, the upper part being shown in section 011 lines 00 m, Fig. 3. j

The letter A designates the draw-head; b, the coupling-pin, swinging on a pivot-bolt, b, and occupying a slot, D in the bottom of the draw-head. The part of the pin below the pivot-bolt forms a weight, 6 which swings in and below the slot b This weight is so much heavier than the pin that it serves to keep the pin upright. A slot, 0, is in the top of the draw-head, and is occupied by a pin-abutment, d, which is pivoted by a bolt, d. When the pin Z1 is against the pin-abutment d, as in Fig. 2, it is in position to hold the couplinglink E firmly, and the pin-abutment isprevented from turning on its pivot by its rear end,d resting on the supportingarm f,which occupies a groove in the top of the drawhead, and has a pivot, f. Vhen the pin 1),

, pin-abutment d, and its supporting-arm f are may uncouple.

in this position, (see Fig. 2,) coupling may be made by means of the ordinary link, E, with another car.

To uncouple the link E from the pin 6, the supporting-arm f must be raised, and thereby release the rear end, (1 of the pin-abutment, whereupon the latter may tilt on its pivot d and allow the pin to tilt forward toward the mouth of the draw-head, and then the link When either coupling or uncoupling, the weights Zr of the pin will take position in the slot b and no damage to the pin can ensue. A spring, 9, on top of the draw-head bears on the supporting-arm f and keeps it down to its seat f. A cross-rod, h, has a bearing on and extends across the drawhead, and a lever, t, is loosely attached to the rod. Achain, 70, connects the supporting-arm f and the lever i. The lever t extends up the end of the car to the top, as shown in Fig. 1, and by means of said lever a person on top of the car may uncouple. The rod It extends from the draw-head to one or both sides of the car, and at the side of the car a lever, Z, is attached to the said rod. Just above the draw-head an arm, n, is rigidly attached to the cross-rod h, and a chain, 0, connects the supporting-arm f and said arm n. By this means a person at one side of the car may uncouple without going between the cars, and as the cross-rod h turns loosely in the end of the lever z the latter will not be affected or moved when the lever Z at the side is used for uncoupling, and vice versa. The pin 12 is broadest at its free end, the sides of which flare, as shown in Fig. 5, and its sides 12 narrow or taper from the end toward its pivotbolt, and each side of the top slot, 0, has a sloping swell or projection, q, below the pivotbolt (1. These sloping projections narrow the slot. By this construction, when the pin 1) is against the abutment d, the flaring sides p of the pin are in the narrowed part of the slot between the sloping side projections, g. In case the pin 1) were to bend in consequence of the strain caused by the link E, its flared up per end would become tight between the sloping side projections, q, and, although bent, it could not slip past the abutment (2..

Having described my invention, I claim and desire to secure by Letters Patent of the United States 1. A car-coupling having, in combination,

a draw-head provided in its bottom with a slot, b a coupling-pin, b, pivoted in the slot, and having below its pivot a weight, a pin abutment, d, pivoted in the top of the drawhead, and a pivoted supporting-arm, f, on which one end of the said abutment rests, as set forth.

2. A car-coupling having, in combination,

a draw-head provided with a pivoted couprately connecting the pivoted arm f with the ling-pin, b, having below its pivot aweight,v said cross-rod arm and lever, assetforth. IO an abutment for the top part of the pin to rest In testimony whereof I affix my signature in against, a pivoted arm, f, to'hold the abutpresence of two witnesses.
